We started using this protocol about a year ago at my facility. Our goal range is 91-120.
While we do have the VAMP system, which I HATE, I find it easier to poke the finger. I wonder how safe it is to be getting blood from the system every hour. I would think entering the supposed sterile system every hour would increase the risk of the line becoming infected. Plus if your art line isn't connected to the VAMP system, which, in our post-op CABG pt, it's not because the art line is in place for about 18 hrs anyway( cost factor) then you're wasting about 10cc of blood each hour. The policy at my facility states that you're NOT supposed to give back the 10cc of blood that you're wasting. The VAMP system eliminates that waste, which is nice.
Our CV surgeons are just now starting to put all of thier diabetic pts on the insulin protocol. Just the other night, I had two pt's both on q 1 hr blood sugars.
